Ingredients
Directions
Prepare the tomatoes

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Form the bulk of the preserve, breaking down during slow cooking into a thick body.
- Brown sugar
- Sweetens the preserve and, as it cooks down, helps thicken it into a syrup.
- Vinegar
- Adds acidity that balances the sweetness and helps keep the preserve tangy.
- Cayenne
- Supplies heat that gives the preserve its spicy character.
The step that matters
Cook slowly until thick. Long, gentle cooking lets water evaporate and sugars concentrate so the mixture thickens. Cooking too hot can scorch the sugar on the bottom of the pot before the tomatoes have softened and reduced.
Swap the tomato
How well each one fits the dish's main ingredients (vinegar, sugar, clove, allspice, cinnamon):
- Mustardfits better
- Horseradishfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against vinegar, sugar, clove, allspice, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
